Home Battery Backup Installation in San Antonio
When the grid goes down in San Antonio, a properly sized battery keeps the essentials — or the whole house — running without a sound. We design battery systems from your actual usage data, install them under our Texas electrical contractor license, and handle the CPS Energy paperwork. Based in Converse, we’re already in your neighborhood.
Backup power, overdue?
Sized with math.
A backup system is an engineering decision: what loads matter, for how long, starting from your real consumption — not a one-size quote. Sometimes the right answer is a smaller battery than you expected. Sometimes it’s pairing storage with your existing solar so the battery recharges every day of an outage. We show the math either way, and we say so when a competitor’s product is the better fit.
We’re Enphase and FranklinWH certified, SPAN smart-panel certified for whole-home backup control, and we service existing installs including Tesla Powerwall systems. Adding battery to solar we didn’t install? That’s a specialty.
Working with CPS Energy.
Battery systems in San Antonio go through CPS Energy interconnection review before they can operate. We handle that process as part of the install — application, documentation, and approval — and we confirm your actual utility first, since territory lines interleave across the metro area.
From load list to lights-on.
San Antonio battery backup, answered.
Can a battery back up my whole house?
Often, yes — with the right capacity and either a smart panel or load management. Whether whole-home is worth it depends on your loads; we show both options.
Will my solar work during an outage?
Standard grid-tied solar shuts off in an outage by design. Paired with a battery, it keeps producing and recharges the battery daily.
Do I need solar to add a battery?
No — batteries charge from the grid and back you up on their own. Solar extends how long you can ride out a long outage.
Does CPS Energy have to approve it?
Yes, battery systems go through interconnection review. We handle the process start to finish.
My battery installer went out of business. Can you take over?
Yes — diagnostics, repair, and monitoring recovery for orphaned systems are a core service line.
